- Hardened drill bits are specialized tools designed to tackle tough drilling tasks that standard drill bits may struggle with. These high-performance bits are heat-treated and hardened to enhance their durability and resistance to wear, making them ideal for drilling through hard materials like stainless steel, cast iron, and even some types of concrete.

“It is of great significance to establish a joint laboratory of composite materials with Sinochem International. The two sides will jointly promote technology development, results transformation and industrial application in related fields such as carbon fiber and solidified resins. We also will explore the collaborative innovation model of the technology joint research of a scientific research institute and an industrial group.”

Our FRP manufacturers in China have more choices for resins selection, and the local production of AOC resins also decreased the supply time and cost.
Jrain will attend AQUATECH CHINA EXPO with the booth No. 7. 1H4155.




Popular resins include economical Corvex polyester, superior Vi-Corr vinyl ester, and other application specific resins. All products are available with the standard concave meniscus surface or optional grit surface (coarse or fine grit).
